I recently bought across America recoil 3 XPS and I changed some things like taking away the the vacuum filters that came with it and replace them with screens this seems to give me even more vac pull and made sure that I put 2 inch hoses to the machine with the cufflinks and the pull get even stronger, but when I decided then I will connect as a booster my Rotovac CFX with a 3 stage and a two-stage vacuum set up that is in it. This setup is extremely great the vacuum and the Cfm is very high I think that it is close to maybe 17 -20 inches of mercury , and about 450 -537 of CfM . I put the recoil 3XPs in the back and have it to pull the Rotovac CFX with 2 inch holes on both ends 25 on the recoil going to the Rotovac CFX + 70 feet of vacuum hose from the Rotovac this setup will allow me too have a continuous flow because the Rotovac have an auto auto dump and it also is very lightweight only have to run one cord from it. I think this is a great setup this will be my first portable truck mount how do this sound to you all. I'm glad I came across this machine I know it may be other machines out here that can do just as well but reliability and good workmanship is what I'm looking for And seems like Cross America company make some good portable Carpet machines.
